Abstract: A conventional single faced corrugated board manufacturing plant is modified to produce corrugated board having two fluted mediums bonded at their flute tips. In addition to the existing corrugating rolls (10, 11) a further pair of corrugating rolls (34, 35) synchronized with the existing pair are provided so that the corrugated mediums (22, 23) are contacted at their flute tips. An additional mill roll stand is provided for the second fluted medium. A carrier roll (36) is provided adjacent to the pairs of corrugating rolls to take off the bonded fluted mediums and provide support and prevent uncontrolled movement of the flute to flute structure during the development of the adhesion bond. Adhesive applicators (37) are provided to apply adhesive to one of the mediums prior to the flute tip to flute tip bonding and to coat the flute tips of the bonded fluted structure on the carrier roll for bonding to the inner (21). An additional guide roll (38) is provided to allow tangential approach for the liner onto the flute to flute structure carried by the carrier roll. Radiant energy is used to assist in bonding the inner to the flute to flute tip structure enabling a low pressure bonding technique to be used.

Granted: 1996-04-09
Abstract: A method of restoring the coherent light transmitting property of a first plate-like transparent medium which has a specific index of  refraction  and whose  surface  irregularities  produce  light scattering image distortion, which comprises the steps of applying a clear hardenable plastic to the said irregular surface, where such plastic has an index of refraction substantially similar to the index of refraction of the transparent medium and then applying one surface of a second separate part of the transparent medium directly to the plastic in adhering relationship thereto, where one of the opposing surfaces of the transparent medium is smooth and becomes the outside surface of a laminate formed by the first transparent medium,  the  plastic  and  the  second  part  of  the transparent medium.    In structural form, an optical system comprising laminated light transmitting plate elements including a first layer having a smooth exterior surface and an opposing inner surface sculptured with forms and figure topographically contouring the inner surface of that layer in a three-dimensional relief, a light reflective film carried by the sculptured inner surface and a second light transmitting layer secured to the inner surface of the first lens layer.  The optical system as described transmits coherent light through the entire body of the system and reflects light from the contoured coating to create an image of the bas relief object to an observer.  Certain light scattering images reflectively coated eliminate secondary light reflections within the lens itself over the area coincident with the coating.

Title: Fuel metering method and apparatus
Inventor: SWANSON MARK S
IPC: F02M5/08
Filed: 1990-10-25
Granted: 1997-12-30
Abstract: Method,  system and apparatus for metering fuel to an internal combustion engine via a carburetor having a mixture conduit with a venturi therein.  A main fuel nozzle supplies fuel to the venturi of the carburetor in response to the static pressure drop induced across an associated main fuel flow controlling restriction by the engine intake induced air flow through the carburetor mixture conduit. A pitot tube is disposed in the venturi with an opening facing upstream in a zone of maximum air  flow through  the carburetor venturi.   A vent passageway system connects the pitot tube to a single closed air chamber cooperable with either a diaphragm or a float to regulate operation of an inlet valve controlling flow of fuel to a main fuel controlling restriction.   The adverse effect of engine intake induced tuning pressure wave forms in the mixture conduit of the carburetor transitting the venturi is eliminated, reduced or modulated by the dynamic pressure exerted by said tuning waves at the pitot tube and transmitted by the vent passageway to said chamber and to said main fuel restriction.

Title: Semiconductor device with reduced time-dependent dielectric failures
Inventor: FISHBEIN BRUCE JEFFREY
IPC: H01L29/94
Filed: 1991-04-15
Granted: 1995-08-22
Abstract: An insulated gate field-effect transistor or similar semiconductor-insulator-semiconductor structure has an increased time-dependent dielectric failure lifetime due to a reduction in the field across the gate insulator. The electric field in the gate insulator is reduced without degrading device performance by limiting the field only when the gate voltage exceeds its nominal range.  The field is limited by lowering the impurity concentration in a poly-silicon gate electrode so that the voltage drop across the gate insulator is reduced.  In order to avoid degrading the device performance when the device is operating with nominal voltage levels, a fixed charge is imposed at the interface between the gate electrode and the gate insulator, so at a gate voltage of about the supply voltage level the response changes to exhibit less increase in the drop across the gate insulator for higher voltages.  Also, the impurity level in the gate electrode may be low enough so that the gate is in deep depletion for transient increases in gate voltage, thereby limiting the drop across the gate insulator.
